SPRING.

, Specification of Letters Patent.

Patented Nov. 3, 1914.

Application filed January 10, 1914. Serial No. 811,468.

To allvwhom it may concern Be it known that I, LAWRENCE A. Avana,

pearas the following description is read 1n connection with theaccompanying drawing which forms a part of this application, an in whichFigure 1 is a top plan view. Fig. 2 is a side elevation. Fig. 3 is avertical sectional view showing on an enlarged 'scale a detail of thespring.

Referring more particularly to the drawing, 1 represents a plurality ofsupporting slats which are connected together at their ends by strips 2which serve to hold the slats in spaced relation.. Each one of 'theslats is provided with a plurality -of perforations spaced apart therequired distance and having slidably seated therein the tubes 3. Thesetubes 3 have their lower ends engaged by the inturned terminals 4 of thespiral springs 5, each of which have their opposite terminals passedthrough one of the apertures in the slots 1 and engaved with the recess6 formed in the upper side of the Slat. Removably mounted 1n the tubesare pins 7 .carrying upon their upper ends the pressure plates 8 whichare apertured in their corners, as shown at 9, to receive the connectinglinks 10. The pins 7 simply hold the pressure plates in position upontop of the tubes 3 and when pressure is applied to said plates it iscommunicated directly to the tube 3, which, slidin through the aperturein the slot, descends t e spring 5.

When the device is used for a bed spring the tubesA and their associatedsprings are spaced a art suiiciently to extend upon opposite si es ofthe slats of the bed and are preferably arranged in transverse andlongitudinal rows, as shown. This arrangement, however, need not becarried out strictly when the spring is used for a seat, but in practicehas been found to be equally as eiiicient constructed in this manner asin any other.

What is claimed is 1. In a spring, a lurality of apertured slatsconnected toget er in spaced relation,

springs depending from the slats, support` mg members passing throughthe apertures and' springs and engaged with the latter, connectedpressu're p ates mounted upon the supporting members and means carriedby the pressure plates and removably engaged' with the supportingmembers for preventlng disconnection of the pressure plates.

2. A s ring comprising a plurality of aperture slats connected togetherin spaced relation, springs passed through the aperturesl and dependingfrom the slats, tubes extending through the apertures and s rings andengaged with the lower end of t e latter, connected pressure platesmounted upon the tubes and pins carried by the pressure plates andremovably en aged with the tubes to prevent disconnection of thepressure plates from said tubes.

In testimony whereof I aiiix my signature in presence of two witnesses.
